Josue Martinez Hardigree

Postdoctoral Researcher in Organic Solar Cells

My interests are in the development of solid-state electronic devices as a means for materials exploration and as an end in their own right. My research centers on understanding how interfaces modify charge transport along and across physical interfaces. My doctoral work focused on dipolar self-assembled monolayers (SAMs) and their role as interfacial agents for manipulating carrier transport in organic field-effect transistors (OFETs).

I am currently investigating microstructural evolution and phase segregation kinetics in organic solar cells, using surface imaging, neutron scattering, and x-ray scattering and spectroscopy. In addition to small-molecule organics, I have worked on characterizing conjugated polymer-based devices and structures, organic insulators, and inorganic semiconductors for a range of devices spanning digital logic, photovoltaics, and display technology.
